FEATURES SEIKO KINETIC Cal. 7L22 is an analogue quartz watch equipped with an Automatic Generating System developed by SEIKO. It generates the electric energy to power the watch, utilizing the movement of the arm, and stores it in the KINETIC ELECTRICITY STORAGE UNIT (KINETIC E.S.U.), which requires no periodical replacement unlike...
POWER RESERVE IN YOUR SEIKO KINETIC WATCH The electric energy generated while the watch is worn on your wrist is stored in the KINETIC ELECTRICITY STORAGE UNIT (KINETIC E.S.U.). It is a power source completely different from conventional batteries for watches, and therefore, does not require any periodical replacement.
REMARKS ON THE KINETIC E.S.U. Do not pull the crown out to the second click with the intention of stopping the second hand just to save energy. By doing so, a large amount of current flows through the built-in IC. Therefore, pulling out the crown to the second click will not save energy but, in fact, consume more energy than usual.
TIME/CALENDAR SETTING Second hand 1. Pull out the crown to the first click and turn it counterclockwise to set the previous day’s date. 2. Pull out the crown to the second click when the second hand is at the 12 o’clock position, and advance the hands by turning the crown counterclockwise to set the desired date.
STOPWATCH The stopwatch can measure up to 45 minutes in 1/5 second increments. The measured time is indicated by two STOPWATCH hands that move independently of the hands for time indication. After 48 minutes, the stopwatch will stop automatically. TIPS ON READING THE HANDS The STOPWATCH second hand turns a full circle in 60 seconds.
